Tribal Nations
The 44 sovereign Native nations whose territories the Corps of Discovery crossed, encountered, or recorded. Each card links to a profile page with biographical synthesis where available, plus entries tagged with that nation. Mention counts come from AI entity extraction across the 3,415 journal entries.
Editorial note: tribal-nation names here use the conventional period spellings used in Lewis & Clark scholarship. We acknowledge that contemporary tribes may prefer different self-designations (e.g. Apsáalooke for Crow, Niimíipuu for Nez Perce). Where known, both forms are surfaced in the individual profile pages.
